Geometry All Around the World

If segment AB is a perpendicular bisector of DC, and angle one is 90 degrees. What is the measure of angle two? What are angles 1 and 2?
What angle can replace the question mark? Also, it is not drawn to scale!
The two bright white lines are parallel to each other. If angle y is 87 degrees, what is angle x? Not drawn to scale.
The white fence wires are all parallel. If angle one is 93 degrees, find out all the other angles. After that, what theorem do you use to prove angles 3 and 4 are congruent?
Are the two black lines parallel? If so why?
What type of construction is shown here?
What postulate can you use to prove that the two roofs are congruent?
Is triangle ABCD similar to triangle FGHE? If it is, why?
What is the measure of one interior and exterior angle of this polygon? What type of polygon is this figure above? Use the orange line to answer the questions.
Are the two orange lines parrallel, skew, or oblique?
Question One= The measure of angle 2 is 90 degrees and angles 1 and 2 are supplementary.
Question Two= The question mark is 110 degrees.
Question Three= Angle x is equal to 95 degrees.
Question Four= Angles 3 and 4 are 93 degrees. Angle 2 is 87 degrees. You would use the corresponding angles are congruent theorem to prove angles 3 and 4 are congruent.
Question Five= They are not parallel because one of distances between the black lines is 31.
Question Six= Perpendicular Bisector
Question Seven= SAS
Question Eight= No
Question Nine= The figure is a Octagon. Interior angle= 135 degrees, Exterior angle= 45 degrees
Question Ten= Skew
